I’m from the Scottish Highlands. I’m built for cold weather, big jumpers and fresh air, not trying to sleep through sticky UK heatwaves with one leg hanging out the duvet while a fan blasts directly into my face all night.

Every summer I forget how badly hot weather affects my sleep until it suddenly arrives. One warm night turns into tossing and turning, waking up constantly, throwing the duvet off, pulling it back on again five minutes later and generally feeling uncomfortable all night.

And because I’m such a light sleeper anyway, bad sleep affects absolutely everything for me. My skin looks dull, my anxiety gets worse, my mental load feels heavier and even my riding goals take a hit because I feel exhausted before the day even starts.

UK houses are also just not built for heat. We’re amazing at trapping warmth in winter, but once temperatures rise everything suddenly feels stuffy and unbearable. Add in midgies coming through the windows at night and honestly it can feel impossible to get comfortable.

Over the last couple of summers I’ve realised the biggest difference comes from the smaller things. Cooling bedding, lighter skincare before bed, keeping the room as cool as possible and, surprisingly, changing what I wear to sleep in.

Heavy pyjamas make everything worse for me in summer. The second fabric starts clinging to my skin I know I’m not going to sleep properly. That’s why breathable sleepwear has become one of the biggest game changers for me recently.

Quick Answer: How To Sleep Better During Hot Weather

If you’re struggling to sleep during hot weather, these are the things that genuinely help me most:

• breathable sleepwear like bamboo or crisp cotton
• cooling duvet covers and lighter bedding
• keeping windows open as much as possible
• using a fan overnight
• lighter evening skincare
• magnesium before bed
• staying hydrated
• avoiding heavy fabrics that trap heat

None of it completely fixes UK heatwaves, but together it definitely makes sleeping feel more manageable.

Why Hot Weather Makes Sleep Feel So Much Worse

I think people underestimate how exhausting bad sleep can be in summer.

When you’re too warm your body struggles to properly switch off, so instead of getting deep comfortable sleep you end up waking up constantly feeling restless and irritated. I notice it immediately in my mood, my concentration and even my skin.

If I’ve had a bad night because of the heat my skin always looks more dehydrated and dull the next morning, and I feel more anxious and overwhelmed throughout the day too.

Being active also makes it harder. After long rides or busy summer days I already feel overheated, so going to bed in thick pyjamas or synthetic fabrics just makes everything worse. That’s why I’ve become much more particular about summer sleepwear over the last couple of years.

The Biggest Thing That Helped Me Sleep Better: Breathable Sleepwear

I never used to think pyjamas really mattered that much. I’d wear old oversized t-shirts or heavier pyjama sets year-round and just deal with feeling uncomfortable in summer. But honestly, fabric makes a massive difference.

I’ve recently been trying a few pieces from British Boxers and they’ve genuinely become some of my favourite summer sleepwear because everything feels lightweight, breathable and comfortable without losing that luxury feel.

The one I reach for most on really hot nights is the Women's Bamboo Strappy Nightdress in Spectra Leopard.

It’s The least clingy option and feels incredibly soft and lightweight against the skin. On those horrible sticky nights where everything feels too warm and uncomfortable, this is the one I automatically grab because I can move properly and nothing feels restrictive.

I also love that it still feels nice rather than looking like an old throw-on sleep shirt. Sometimes comfortable sleepwear can feel a bit frumpy, but this still feels elevated and put together.

The two cotton pyjama sets have probably become my favourites for travelling in the van conversion and summer trips, though.

The British boxer's women's Crisp Cotton 3/4 Marrakesh Paisley set and Shell Pink Satin Stripe set both have that crisp, cool cotton ( yes, the name fits it perfectly) feeling that reminds me of fresh hotel bedding. They feel airy and breathable while still looking really polished.

That’s something I genuinely appreciate when travelling because if Mylo needs out early in the morning or I’m sitting outside with a coffee, I still feel properly dressed rather than like I’ve just rolled out of bed.

They’ve also become really nice summer lounge sets on warmer evenings at home because they feel cool on the skin without looking overly casual.

Bamboo vs Cotton Pyjamas for Summer

If you’re trying to decide between bamboo and cotton sleepwear for summer, I honestly think both work brilliantly, it just depends on what you personally find most comfortable.

For me, bamboo works best during really hot sticky nights because it feels softer, lighter and less clingy when the weather becomes unbearable.

Cotton feels slightly crisper and cooler in a different way. It has more of that fresh breathable hotel bedding feel, especially if you prefer more structured pyjamas.

I’ve found myself reaching for bamboo when I feel overheated and restless, but choosing cotton sets more for travelling, lounging and general summer evenings.

Other Things That Have Been Helping Me Stay Cooler At Night

I wish I had some revolutionary answer for sleeping during UK heatwaves, but honestly most of it is just trial and error and trying not to get annoyed at 2am.

One thing I’ve noticed is how much heat builds up in UK houses during the day. Especially upstairs. By bedtime the room somehow still feels warm and stuffy even if the temperature outside has dropped hours ago.

I’ve started keeping blinds shut much earlier in the day now, which definitely helps stop the bedroom turning into an oven. Then at night, it becomes a balancing act between opening windows for cooler air and deciding how many midgies I’m emotionally prepared to deal with before sleep.

I also swapped over to lighter cooling duvet covers this year, which has helped more than I expected. I used to just keep the same bedding year-round but heavy bedding makes me feel trapped once it gets warm. Some nights I end up with one leg out the duvet, other nights I’m cold again five minutes later. There’s absolutely no consistency.

I’ve also realised that really heavy evening skincare can make me feel even warmer before bed in summer. In winter, I love rich moisturisers and thick overnight masks, but during heatwaves I want everything to feel lighter, fresher and more cooling on my skin.

Hydration makes a massive difference, too, especially after riding or spending the day outdoors. If I’m even slightly dehydrated, I sleep terribly in hot weather. And my Dyson fan honestly deserves employee of the month at this point. I pretty much have it running all evening once temperatures start climbing.

Magnesium before bed has also become part of my routine most nights because I find it helps me relax a bit more, especially when I’m already overstimulated and uncomfortable from the heat.

But genuinely, changing my sleepwear has probably helped most overall.

The second fabric feels heavy or clingy I know I’m going to struggle sleeping properly. Lightweight breathable fabrics just feel so much more comfortable when you’re already too warm and restless.

Final Thoughts

I don’t think I’ll ever be someone who enjoys sleeping in hot weather. I’m definitely more suited to cold Highland temperatures than overheated summer nights.

But I’ve realised recently that small comfort changes genuinely make a difference, especially when it comes to breathable sleepwear and lighter fabrics.

The British Boxers pieces have honestly been such a nice upgrade for summer because they feel luxurious and elevated without being overly expensive, and more importantly, they actually feel comfortable to sleep in when the weather gets unbearable.

And when sleep affects your skin, anxiety, energy levels and overall mood as much as it does mine, those small changes start feeling very worth it.

FAQs

Why is it harder to sleep during hot weather?

Hot weather makes it harder for your body temperature to properly cool down at night, which can leave you feeling restless, uncomfortable and constantly waking up. I definitely notice I sleep much worse during UK heatwaves, especially because I’m already such a light sleeper normally.

What is the best fabric to sleep in during summer?

For me, breathable fabrics make the biggest difference. Bamboo feels incredibly lightweight and less clingy on really hot nights, while crisp cotton pyjamas have that cool fresh bedding feeling that feels much more comfortable in warmer weather.

How can I stay cool at night without air conditioning?

Most UK homes don’t have air conditioning, so small changes help more than people realise. I keep blinds closed during the day, use lighter bedding, sleep with a fan on, keep water beside the bed and wear breathable sleepwear instead of heavier pyjamas.

Are bamboo pyjamas good for hot sleepers?

I genuinely think bamboo sleepwear is brilliant if you struggle with overheating at night. The fabric feels soft, breathable and much lighter against the skin compared to heavier pyjamas that can start feeling sticky in warm weather.

What actually helps you sleep better during a UK heatwave?

Honestly, it’s usually a combination of things rather than one miracle fix. Cooling bedding, breathable pyjamas, a fan, lighter skincare and staying hydrated have all helped me feel much more comfortable during hotter nights.

Should you change your skincare routine during hot weather?

I definitely do. During summer and UK heatwaves I find heavier skincare can start feeling uncomfortable before bed, especially if the house already feels warm and stuffy. I usually switch to lighter hydrating products, cooling textures and make sure I’m consistent with SPF during the day because heat, sun exposure and dehydration can leave my skin looking dull really quickly.
